A thermal printer (10) with a thermal head (16) for image-wise heating a heat-sensitive sheet according to an elongate printing zone, which comprises sheet feeding means having a sheet advancing mode for feeding a sheet with its leading end through the gap between the print drum (15) and the thermal head (16) of this printer beyond the position it should take at the start of printing, and a sheet-returning mode in which the sheet can move backwardly, and a stop (44, 52) against which the backwardly moving sheet abuts with its trailing edge for its longitudinal alignment, thereby to obtain with its leading end the correct printing start position in the gap.

Thermal printer with sheet feeding means

Thermal printer with a thermal head (16) for image-wise heating a heat-sensitive sheet (38) according to an elongate printing zone, transverse with respect to the sheet, and a rotatable print drum (15) for conveying such sheet past such thermal head while the head is urged towards the drum, which is provided with a pressure roller (17) for urging a sheet section, downstream of the printing zone, onto the print drum in order to establish a contact angle alpha between the sheet and the print drum.
